Jiyoon is an ordinary girl who lives in a pretty normal life. Although her family isn't very wealthy and doesn't own a lot of material riches, her parents still strived for her to study in a prestigious academy for the sake of having a good educational background. Jiyoon thought that everything would be fine as long as her family and friends are there, but it turns out that it's not exactly what she wanted upon learning that she's supposed to marry a guy named Donghae, a very rich student in their school who's known to be the grandson of the founder of their school, and is Jiyoon's most despised guy. Her life is about to take on a new spin as she slowly lets herself fall in the complicated environment of love, and accepting things which couldn't be changed as they were planned to be.
